Has anyone come across this formula to calculate the minimum kernel speed you require. It seems if 40ipm cutting and 80ipm rapids are all you need then a kernel speed of 26K should do.
If you want to calculate out your max pulse frequency start with the max velocity of your machine.
Max_Velocity(IPM) * Steps/Unit = max_step_min (a.k.a. #steps in one minute at max velocity)
max_step_min / 60 = max_pulse_frequency
Your kernel frequency needs to the the lowest choice you have that is greater than your max_pulse_frequency.
